Specification of Letters Patent.

Patented Mar. 3d, 1915.

Application filed may 8, 1913'. Serial Ito. 766,357.

To all whom it may concern:

Be it known that I, FERDINAND WEBB, a

citizen of the Unitedv States, residing at Stewartsville, county ofPosey, and State of Indiana, have invented certain new and usefulImprovements in Trammel-Wheels, of which the following is aspecification.

This invention relates to trammel wheels.

The/object of the invention is the provision, first, of an improvedtrammel wheel; second, of improved lubricating means for trammel wheels;third, the provision of a trainmel wheel having improved lubricatingmeans for the wrist pins and slides.

The invention consists of certain improved features and combinations ofparts set forth fully hereinafter.

1n the accompanying drawings :-F1gure 1 is'a face view of the trammelwheel with the slides and connecting rod removed; Fig. 2', an edge viewthereof; Fig. 3, a face view of the complete trammel wheel, sl1des, andconnecting rod; Fig. 4, a detail plan view of one of the slides; Fig. 5,a section on line 5.5, Fig. 4; and Fig. 6, a detail view showing the,means for lubricating thewrlst pin and the slide.

My invention relates to those devices known astrammels which are adaptedfor convertingreciprocating into rotary motion with a large increase ofpower and speed.

The trammel wheel 1 is provided with dove-tailed channels or seats 2 and3 which are arranged at right angles to each other and intersect at thecenter of the wheel, the latter being carried by a shaft 4 through whichany mechanism may be driven, or, the shaft 4- may he the driter forconverting its rotary motion into a reciprocating motion of theconnecting rod 5.

The slides 6 and 7 are provided with beveled edges 8 and'fit and slidein the dove tailed seats 2 and 3, respectively.

Referring to Figs. 4 and 5, each slide has a rigid orintegral wrist pin9 projecting from its outer face, said wrist pins being received inbearings 10 and 11 on the connecting rod 5. The bearings may be linedand of any preferred construction. The connecting rod is provided withoil cups or lubricators 12 and 13 which communicate with ports leadingto the bearings aforesaid, whereby lubricant is supplied in proper orsuitable quantities to the bearings and the wrist pins.

The slides 6 and T are provided with lu bricating ducts 1&- running fromtheir outer to their inner faces, said ducts being arranged with theirreceiving mouths 15 along side the wrist pins and under the connectingrod 5 in line with thebearings 10 and 11, respectively, so 'that thelubricant after passing to the bearings from the cups 12 and 13, worksdown through the ducts 14 and out at 16 into the channels 2 and 3,causing lubrication of the slides as they play in the aforesaidchannels.

The outer ends of the channels 2 and 3, being open, and the slides beingadapted to project beyond the periphery of the trammel wheel 1, as shownin Fig. 3, the lubricant drains by centrifugal action out through theends of said channels, thereby preventing guinming and tending to keepthe channels relatively clean. Any suitable means such as the nuts andgibs 17 may be employed on the wrist pins 9 to hold the connecting rod 5thereon.

The present invention is adapted for use in any connection where it isdesired to convert a reciprocating motion into a rotary motion with anincrease in' power and a very great increase in speed, and it is adaptedfor use on direct connectedelectric generator sets as the connecting rod5 will be driven by the piston of the engine and the shaft 4 will bedirectly coupled to the electric generator which may then be driven athigh speed with the same fuel consumption as if driven at the same speedas that of the engine.

'Having no face plate or parts other than the trammel wheel, the slidesand the connecting rod 5, friction is minimized and the constructionmade more durable and less expensive than other trammels while, at thesame time, the system of automatic lubricationv insures the greatestease of operation, resulting in very small wear.

Having thus described my invention, what 1 claim as new and desire tosecure by Letters Patent, is

In a trammel, the combination with a trammel wheel having intersectingchannels, of slides movable in said channels and having wrist pins, aconnecting rod jourranged to feedthe lubricant to the wrist pins, whenceit passes into the ducts afore- 10 said.

In testimony whereof, I hereunto afi'ix my signature in presence of twowitnesses.
